CHART HOLDER.

Application led February 7, 1921. Serial No.442,944.

My invention relatesto chart holders and consists ina casing, and clips adapted to' be inserted therein to yhold charts, maps, samples of paper, cloth or other thin sheets whether flexible orrigid.v e

TheL main object of invention is to provide ,a simple, economical holder which is adapted to suspend charts, etc., and to permit substitution, ,and variations in the number of charts.

Such a holder must be large enough to accommodate a predetermined, maximum number of sheets and another object of my invention is to provide means for suspending a lesser number of sheets as securely and in the same position as if the holder was full. v

In the accompanying` drawings illustrating my1 invention Y Fig. 1 is a rear elevation of my holder showing some sheets suspendedvand partl of a supporting stand.

Fig. 2 is a vertical, transverse section on the line 2-2 of Fig. 1.

Fig. 3 is arear elevation of one ofthe clips.

F ig. et is a vertical, transverse section on the line el-il of Fig. 1 and Figs. 5 and 6 are respectively rear and side'elevations of a modified ferm of clip.

The holder casing 1 is formed substantially from a single plate bent to the forni shown in Fig. 2 which comprises vertical spaced walls 2 and 3 united by the top 4. The lower end of front Wall 2 is bent upwardly at 5 to form a groove 6. r1`he upper portion of the rear wall 3 is bent outwardly to form a recess 7 which provides wall 3 `with an upwardly facing ledge 8.

The ends of the casing comprise sheet metal stampings 9 and 10, each in the form of a shallow cap having the outline of a cross section through the casing. lilhese may be screwed or riveted to the casing as indicated at the left `hand of Fig. 1. Preferably one of them, at least, is removably secured to the casing by tongue and slot means as indicated at the right hand of i and damned in rig. 4. with uns latter construction, the walls 2 and 3 are provided with outwardlyprojecting tongues preferably stamped therefrom lwhich are adapted to enter corresponding recesses formed in the cap 10 to hold the latter in place. By springing the walls v2 and?) slightly'inward the tongues are withdrawn from the recesses permitting the cap 10 to be slipped from the end of the casing.

Each clip 12 preferably consists of a one piece elementk bent so as to have substanv tially the same shape as casing 1 butsomewhat smaller and without the upturned iiangeV of the latter. The clip is formed ofv flexible material and has an integral tongue 13 stamped kfrom one leg 1&1-, thereof. The opposite legl is provided with a slot through which tongue 13 may be passed.

Fig. 2 showsv casing 1 and clip 12 assenibled.r The full line position of clip 12 indicates its shape and location whencomparatively few lsheets are mountedin the holder and the dotted line position representis it when the holder is lled tol maxi? mum capacity.

It will be noted that. the lower edge of front leg 15 of the clip is supported and rretained in the groove 6 of the casing and that the shoulder on the rear of the clip is supported on the ledge 8 of the casing. Thisis true whether the clip legs are close together or .far apart as the rearwardly e.\:-v

tending portion'of the clip always remains within the casing recess 7 and rests upon the casing ledge b. y The flange 5 on the front casing wall retains the front leg 15 of the clip and consequently the suspended sheets are always adjacent the front of the casing.

intermediate the ends of casing 1 on its rear side is a bracket 16 adapted to receive the upper end of a lrod 17 which forms part of a pedestal for supporting the chart holder. 1f necessary, the casing may be reinforced at this point by a stiifening plate 18.

While, as mentioned above, the casing walls 2 and 3 may be sprung suliciently to release tongues 11 from the slots in the end caps, it is to be understood that the casing is substantially rigid so that it retains its shape irrespective of the load which it may support.

ln the clip illustrated. in Figs. 5 and G, a bolt 19 is substituted for the clip tongue.

Vhere 'frequent insertions or removals ot sheets are required this construction will be advantageous as repeated bending' of tongue 13 would result in -fracture of the tongue.

The sheets to be mounted in the holder are lirst gripped by two or more of the clips spaced from each other and the clips with the upper ends or the sheets are slid into the casing endwise and the removable cap positioned on the casing. lVhen it is desired to replace one of the sheets or insert an additionalsheet the cap is removed and the clips` and sheets are withdrawn through the open end of the casing, the clips opened, thenew sheet, placed in position and the clips reassembled vand thef sheets and clips reinserted in thecasing.

It will be apparent that various changes may be made in the form, constructionand arrangement ofthe parts without departing from the spirit and scope of my invention or sacriiicing any of the material advantages tliereolfand I reserve the right to make all such changes as `fairly ,tall within the scope of the following claims.

I claim: f p l. ln a chart holder,` a casing having a longitudinal groove and a longitudinal ledge, and a chart clip supported by said Casing, and having a leg to rest in said groove, and` a shoulder; to lie on said ledge.

2. ln a chart holder, a casing and a chart clip, said clip having a` downwardly ex*k tending leg and a rearwardly extending shoulder, and said casing having an upwardly facing groove to support the end et said leg, and a ledge to support said shoulder. i

3. In a chart holder, a casing and an ad-y justable chart clip, said clip having a downwardly extending leg anda rearwardly eX- tendingA shoulder, and said casing having an upwardly facing p roovel to support the edge oi said leg, and a ledge adapted to support said shoulder irrespective ot the adjustment oft said clip.

L ln a chart holder, a casing comprising LLM-inea a plate bent to provide spaced, vertical walls, one wall being provided with an upwardly facing groove at its lower edge and the other wall being provided with an inner .recess adjacent its upper edge, and a chart clip comprising a strip bent to provide spaced legs, one leg having its lower edge supported in said groove and the other leg being` provided with an external shoulder seatedon said recess.

5. n a chartv holder, a casing having an open bottom, and an open end, a chart clip adapted to be inserted in lsaid casing through said end and tobe supported by said casing and a cap removably secured to the open end o'l said casing.

6. ln a chart holder, a rigid casing having an open bottoni, and a ilexible chart clip adapted to be inserted'tlnough an end of said Acasing and means for supporting said clip within said casing.

7. ln a chart holder, a longitudinal casing and a clip adapted to grip one or more chartr sheets, said casing being adapted to receive through its end the upperk edges, et

one or more chart sheets and to receive through its end and to supportsaid clip.

8. ln a chart holder, a licxible :flip adapted to securely grip one or more chart sheets and a casing having an open bottom and adapted to hold said clip in a predetermined position irrespective of the number oi sheets it may grip.

9. ln a chart holder, a rcasing having` spaced walls and an opening between the lower portion oi said walls, a clip having spaced legs and chart suspending means between said legs, said casing walls being pro.

vided with clip supporting means.

10. ln a chartholdeiga casing having a longitudinal groove and ay longitudinal ledge, and a plurality of clips adapted to suspend chart sheets and to slide along said groove and ledge and to be spaced troni each other lengthwise oit the casing by the sus` pended chart sheets. y
